It looks like ATF is waving a white flag. They're backing down when it comes to banning AR-15 ammo.That's a big relief to people at Fort Worth Gun who were busy buying bullets before the ban. But, after gun groups went up in arms about the proposed ban, the ATF decided not to target what they call armor piercing ammo after all. Well, ATF will take comments until Monday ... So, the battle might not be over just yet!
